Возвращает тип узла.
public:
virtual property System::Xml::XmlNodeType NodeType { System::Xml::XmlNodeType get(); };
public override System.Xml.XmlNodeType NodeType { get; }
member this.NodeType : System.Xml.XmlNodeType
Public Overrides ReadOnly Property NodeType As XmlNodeType
Значение свойства
Для узлов XmlWhitespace
значение — Whitespace.
